What is CNC Prototyping?

Computer numeric control is referred to as CNC. As a result, CNC prototype machining is a process in which a computer operates a machine tool following numerical data entered into the machine. Most often, CAD/CAM software is utilized, which enables technicians to build the required design and then enables the computer to control the movements of the tool. The computer can also manage various machining tools, including lathes and drills, to help produce the desired outcomes. This technique is essential for manufacturing industries as it enables them to develop product prototypes and other items that meet specific requirements. Although there are alternative prototype methods, such as 3D printing, CNC prototyping can use a wider variety of materials.

Additionally, this technique is best suited for complex and mechanical components. CNC milling, CNC turning, and CNC screw matching are a few examples of CNC prototype machining techniques. Each fully utilized computer-controlled technology to produce highly specific and detailed prototypes.

Applications of CNC Prototyping

Almost all industries where precision machining is used can benefit from CNC prototype machining. In most of these businesses, a working prototype is always required, or at the least, a model that can demonstrate how the final product will operate. Machined tooling is extensively used in the following industries as it is frequently preferred for functional prototypes requiring strength, mechanical stability, or other qualities that additive techniques cannot provide.

Automotive Industry

Automobile manufacturers often work on new ideas and must create prototypes for new technologies before putting them on the production line. Before going into mass manufacturing, they must test these prototypes to ensure they work and fit well inside the automobile, much like in the medical sector. These prototypes are developed using CNC machining with accurate specifications to deliver the best results. CNC prototyping also produces components for various modes of transportation, including trucks and commercial ships.

Defense and Military Industry

CNC prototypes are widely used in the military industry to develop prototypes for weapons and military vehicles that are relatively complex devices to function. This computerized method helps mitigate the chances of actual accidents caused by the manual workforce. Equipment created through this technique includes weapons, airplane parts, vehicles, and communication components.

Medical Industry

As medicine is rapidly improving and evolving every day, there has been a surge in demand for new equipment. But before its actual use, medical businesses will demand to see a prototype of the product. This helps ensure that the product will genuinely serve the intended purpose and has a high tolerance. Since it deals with actual lives, there isn't much room for mistakes; thus, the prototype must be an identical, functioning version of the final product. These are designed using a CNC prototype to guarantee defined results. Some equipment made from this process includes orthotic devices, secure enclosures, implants, MRI machines, research instruments, etc.

Aerospace Industry

The aerospace business does not tolerate even the slightest error since one minor mistake might result in drag in some aircraft elements or extend the wear of some parts. This makes CNC Prototyping the ideal candidate for developing prototypes with a high level of accuracy, which is much needed for the aerospace industry. This will help test its functionality before the component is used in an actual aircraft. Numerous features in this industry, including landing gear ports, airfoils, bushings and manifolds, are made using the CNC prototype machining technique.

Advantages of CNC Prototyping

Faster processing time

This technique produces the fastest and most reliable results, with both the setup and processing times dependent on its speed. Firstly, the latest CAD/CAM design software is used to create a 3D part that can be converted into a G-code cutting program and then transmitted to a multi-axis mill in a few hours. Once programmed, a quality mill or lathe can quickly transform a raw metal blank into a final product by carving through steel or aluminum at an accelerating pace.

High accuracy and tolerance

CNC Prototypes deliver a high degree of precision with tolerances of +0.05mm or 50 microns. For the vast majority of commercial applications, this level of accuracy is more than enough and makes it identical to the final product. Additionally, this tolerance is consistent and straightforward to establish throughout manufacturing runs with a limitless amount of product numbers.

Cost-effective

If you need to produce a few prototypes, CNC machining is the most cost-effective choice. Compared to injection molding, where it may take months to prepare the mold and tolerances, CNC prototype machining can start immediately as soon as the layout and tolerances are finalized just a few weeks later.

No fixed tooling is required

Compared to injection molding and die casting, CNC Prototyping does not require additional tools. This helps eliminate any initial investment cost and lead time during the phase of new product development. The sole equipment for CNC milling and turning is the hardened metal cutting inserts for spindles. Various cutting inserts and shapes perform different cutting operations on the equipment, but when appropriately arranged on an automated turntable, these tools can be switched and exchanged within seconds.

Easy to modify

Modifying a few lines of the G-code software is needed to make minor tweaks or modifications to a new prototype's initial design. CNC Prototyping also allows you to try out numerous different versions and evaluate the outcomes immediately. The total lead time for product development can be reduced drastically by fine-tuning the program and making improvements while in the process without incurring additional costs.

Material selection

CNC machines are unconcerned with the type of material they are cutting as long as the material is hard enough to resist deforming or melting under the pressure of the cutting process. This can be useful during product development or when creating several identical prototypes with slightly different mechanical or aesthetic features. For instance, the exact design may be produced using hard plastic, aluminum, or steel with minor changes to the speed and input of the cutting tool.

For accurate prototyping of products or components, our CNC prototyping technology is the best production method as its advanced technology strictly follows design guidelines and produces parts within a short lead time. CNC prototyping is a desirable choice if your company intends to produce products with a brief window for human error and very specified requirements. With on-demand assistance and unlimited production capacity, you can minimize downtime spent having to wait for components to be completed. Our efficient prototyping and manufacturing services significantly save your production costs while speeding up your launch time.

CNC Prototyping FAQs

Is CNC prototype machining the best way to develop prototypes?

The material for the task, the prototype’s structural soundness requirements, and other criteria all play a significant role in the decision to use machined tooling for your work. However, CNC prototype machining is one of the ideal solutions if you want the prototype to be highly durable and identical to the final product.

How is the cost of my CNC prototype project calculated?

Any CNC prototype project will cost more or less depending on the type of material used, the cost of the material, the amount of time needed to process the material, the type of tolerances required, if hole tapping is necessary, and the surface texture desired.

How can I reduce any additional cost for CNC Prototyping?

  • Use inner radii at the corners of your designs and avoid designs with sharp internal corners.
  • Design all components with standard sizes if possible. For example, it is more affordable and economical to produce parts 10 meters tall than 10.5 meters, as the latter involves manual input.
  • Avoid deep pockets in your design as it removes much of the material resulting in additional cost.
  • Make sure to design parts without drafting.
  • Reduce the number of angles and sides the part must be machined by simplifying its design. The cost of part machining would increase with additional angles, axes, and sides.

What is the standard tolerance for CNC machining operations?

At Premium Parts, we manufacture parts to the general tolerances of DIN ISO 2768. We employ the fine-class tolerance standards for metal machining, and for plastic, we use the medium-class specifications as a guide.

Can I provide the raw materials?

Yes. However, to ensure that the material can be machined, we must analyze and identify it.

How can you manage parts with complex structures when using plastic?

For the CNC machining operations, we separate the pieces and use high-quality adhesives to assemble them.

What kind of plastics do you use for adhesives during CNC prototyping?

Typically, glues and adhesives are used to bind PC, ABS, PMMA, and PC/ABS.

What type of finishing can I expect on the parts of the prototype?

CNC-machined parts are typically delivered without marks or oxidation if no finish specifications are provided. Components may be polished with sanding techniques or left as machined. The use of the pieces will determine the type of finish.
